<H2 CLASS="section"><A NAME="htoc135">B.5</A>&nbsp;&nbsp;Operations on ECL<SUP><I>i</I></SUP>PS<SUP><I>e</I></SUP> Data</H2>
Interfaces to some basic operations on ECL<SUP><I>i</I></SUP>PS<SUP><I>e</I></SUP> Data.
<DL CLASS="description" COMPACT=compact><DT CLASS="dt-description">
<B>int		compare(const EC_word&amp; pw1, const EC_word&amp; pw2)</B><DD CLASS="dd-description"><BR>
	Similar to the compare/3 built-in predicate:
	returns 0 if the arguments are identical,
	a negative number if pw1 is smaller than pw2,
	and a positive number if pw1 is greater than pw2
	in the standard term ordering.<BR>
<BR>
<DT CLASS="dt-description"><B>int		EC_word::schedule_suspensions(int)</B><DD CLASS="dd-description"><BR>
	Similar to the
	<A HREF="../bips/kernel/suspensions/schedule_suspensions-2.html"><B>schedule_suspensions/2</B></A><A NAME="@default388"></A>
	built-in predicate.
	Waking will only happen once control is returned to ECL<SUP><I>i</I></SUP>PS<SUP><I>e</I></SUP>
	and the wake/0 predicate is invoked.
	Return code is EC_succeed or an error code.<BR>
<BR>
<DT CLASS="dt-description"><B>pword		EC_word::free_handle(const t_ext_type*)</B><DD CLASS="dd-description"><BR>
	checks whether the EC_word is an ECL<SUP><I>i</I></SUP>PS<SUP><I>e</I></SUP> external data handle of the
	expected type, and calls its free-method. After doing that, the
	handle is stale and cannot be used any longer. Calling this method
	on an already stale handle silently succeeds.
	Return code is EC_succeed or an error code.</DL>
